Porous and bioactive polyetheretherketone (PEEK) scaffolds have potential to replace metallic scaffolds for biologic fixation of permanent implants adjacent to trabecular bone, such as interbody spinal fusion devices. The objective of this study was to investigate the effects of the mold temperature and PEEK powder on the mechanical properties and crystallinity of hydroxyapatite (HA) whisker-re...

Edge race-tracking is a frequently reported issue during resin transfer molding. It caused by highly permeable channels and areas between the preform edge cavity, which can significantly change impregnation pattern. To date, information scarce on effect of in compression molding (CRTM). close this gap, laboratory equipment was developed to study CRTM via flow visualization experiments. The ther...

Polyetheretherketone (PEEK) was reinforced with 0-50 vol% hydroxyapatite (HA) whiskers using a novel powder processing and compression molding technique which enabled uniform mixing at high whisker content. Texture analysis showed that viscous flow during compression molding produced a preferred orientation of whiskers along the specimen tensile axis. Consequently, the elastic modulus or ultima...

The compression molding process of carbon fiber sheet compounds (CF-SMC) is characterized by a squeeze flow the material. There are no standardized measurement methods to characterize behavior CF-SMC and conventional shear-flow dominated plastics processing not suitable describe elongational deformation mode during molding. objective this work was develop methodology determine rheological prope...

Creation of recycle-based society is an important factor in order to resolve geoenvironmental issues that are happening recently. A general recycling method for wooden materials is to make engineered board from wasted woods. For example, particle board, fiber board, ply board are used widely in architectural industry and so on. However, these boards contain chemical compounds such as urea resin...

Nowadays, nanoscale innovations in the forms of pathogen detection, active packaging, antimicrobial packaging and barrier formation are poised to elevate food packaging to new heights. Antimicrobial nanocomposite LDPE films containing ZnO nanoparticles at different concentrations (e.g. 1%, 3%, 5%  and 3%  nano-ZnO pulse 10% polyethylene grafted maleic anhydride (PE-g-MA), w/w pure LDPE), were p...

In this work, polypropylene (PP) was foamed via rotational molding using a chemical blowing agent (CBA) based on azodicarbonamide over range of concentration (0 to 0.5% wt.). The samples were then analyzed in terms morphological, thermal and mechanical properties. morphological analysis showed continuous increase the average cell size density with increasing CBA content. Increasing content also...
